When I first started this it was fine…except I failed to look behind to occasionally see what the path looked like going back. You would be amazed how different things look 180 degrees from your heading. One time I decided I’d put little reflectors on trees on my way out so if I was coming back after dark I could just follow the illuminated dots. All went well for the first 150 yards till I found that someone had the same idea and I was following his/her trail instead of my own. I didn’t have to follow it too long before I saw I was veering off course and then made a correction and got back to camp several hours past dark. The moral to the story is, if you’re in unfamiliar country, make sure you have a backup plan in the event your GPS quits working or someone moves the North Star!
